face="Times New Roman Star"EDT 313, VEWT 55. Cf. the name of the Xiongnu shanyu, MC ma^w-ton (*mag|u-tur). This Turkic word was borrowed into numerous surrounding languages (Iranian, Mongolian etc., see the literature in Ё—“я). Modern forms like batyr, batur are back-borrowings from Mong.; forms of the type baxatir - back-borrowings from Persian.

face="Times New Roman Star"Ё—“я 2, 107-108. Cf. perhaps also Yak. bet-tex (Dolg. bettek) 'here, closely', Yak., Dolg. betere: 'this, nearest side' (although it may go back to *bet 'face'; derivation < *be-ru" 'this side' in Ё—“я 2, 124, followed by Stachowski 59, is hardly plausible). The sometimes proposed explanation as *bu ile, i.e. "together with it" or "by means of it" is not quite acceptable for semantic reasons. As for the Oghuz variants with a labialized vowels, they may have an assimilative origin. But on the whole the attribution of the Turkic form is still dubious (although the semantic derivation "similar, such as" < "face, looks" seems to be quite common in Altaic).
